The prevalence and distribution of osteoarthrosis has been studied in a South African Negro population. One or more joints were affected in 60% of the males and 48% of the females, compared with a prevalence of 55% in males and 63% in females in a comparable English population. Multiple osteoarthrosis was significantly less common in the African than in the English population, the difference here being greatest in females. Clinical Heberden's nodes were also very infrequent in the African population. However, the Tswana males had significantly more osteoarthrosis of the metacarpophalangeal and proximal interphalangeal joints than was encountered in English males. This is attributed to the traumatic effect of hard manual work which is carried on into old age among most African populations.
在南非黑人人群中对骨关节炎的患病率和分布情况进行了研究。60%的男性和48%的女性有一个或多个关节受累，相比之下，在与之可比的英国人群中，男性患病率为55%，女性为63%。多关节骨关节炎在非洲人群中明显比在英国人群中少见，这种差异在女性中最为显著。临床赫伯登结节在非洲人群中也非常少见。然而，茨瓦纳男性掌指关节和近端指间关节的骨关节炎明显多于英国男性。这归因于繁重体力劳动的创伤性影响，这种劳动在大多数非洲人群中会持续到老年。
